“Proto-MSA *ˁamal- must be identical to Arb.
ˁamal- ‘work, labor’ (and PCS
*ˁamal-). In Classical Arabic this term does not seem to display any agricultural meaning which is, however, well attested in the Arabic dialects of Southern Arabia (Landberg 1901:663, GD 2330‒2331, Behnstedt 867, Piamenta 341, Rhodokanakis
41). In such conditions, it is hard to say whether we are faced with a (relatively
early?) Arabic loanword into individual MSA languages or rather with
a Proto-MSA term which influenced the local Arabic dialects. Admittedly, the
phonetic shape of the Soqotri word (final stress, the “soft” lʼ) rather unambiguously
speaks in favor of the the first possibility.” (Kogan 2015:549)
